' in the body. Therefore, it is an object of this invention to provide an unloading .device of the movable floor type whlch requires 5 a minimum of power for its operation.

It is another object of 'thisinvention to provide a load receiving body having adjustable'side walls adapted to be inclinedv toward a discharging'device during the unloading operation to insure the complete discharge of the body load and at the same-time permit maximum load capacity when the walls are in normal position.

A further object of this invention is to pro-l vide an attachment for unloading devices whereing the material may be readily discharged into buckets, sacks or other containers at approximately shoulder height in order to facilitate the carrying of the material from the body to a place of storage.

A still further object of this invention is to provide a device ofthe character described which may be either'manually or mechanically operated, which may be applied tothe trucks now in use or to the trucks at the time of their manufacture, and which is applicable to wagons, trucks, railway cars and the like.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of partssubstantially as hereinafter described and more particularly defined by the ap-` pended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my v invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

principles of my invention manual means or, ao-.

Referring now more particularly'lto the I.

accompanying drawings in which like numerals designate like parts throughout the several views, the numeral 10 designates the chassis frame of an automotive truck which is supported at its rear by drive wheels'll and at its forward end by steering wheels, not shown. Mounted on the chassis frame unit, not shown, l illustrated by conventional lines, is a load receivingbo'dy supporting frame com rising longitudinal side channel beams or si ls 13 suitably seouredto the chassis frameand carrying, at spaced intervals, transverse bars or I-beams 14 upon which is mounted a load receiving body 15.

The load receiving body is constructed of a plurality of spaced vertical beams or braces 16 having their lower ends secured to the transverse beams 14 and their .upper ends -connected by channel irons, or other connectframe which is closed at its inner end by an end plate 18 and at its outer discharge end by an end plate 19 provided with a hinged discharge gate`20. The sides of the body each comprise a pair of members or plates 21 and 22 hlngedly connected, as at 23, plate 21 extending throughout the length of the body and havlng its longitudinal edge pivotally connected to a longitudinal beam 24 fixed to the beams 14, as at 25, near the adjacent side of a movable licor member 26, to be later described. l

Each plate or member 22 is of a width aproximatel equal to the height of the body ame and as its outer portion inclined outwardly and then laterally to, with a bracket member 27, provide a track for a roller .28 journaled in a bracket I29 fixed to the adjacent channel iron 17. Roller 28 prevents the falling inwardly of the sides when in load `receiving osition and provides anti-,friction means or supporting the weight of the sides .when moved to the dotted line position depicted in Figure 2. Each plate 22 is preferably provided with two or more bracket members 27 as illustrated in Figure 1. `When the body is in load receivin(1r condition, the wall sections are in the full line positions-depicted in Figure 2 with the outer ends of the tracks formed by brackets 27 and the adj acent portions of the plates nested on the channel irons 17,'and the point of connection between -the plates 21 and 22 forming an angle to define the junction of the body sides and bottom.

Each hinge n23 has its part secured to the plate 21 on the inner face thereof and its part secured to the plate 22 on the outer face thereof, whereby the inner edges of the plates 2.2 are tight with and overlap the plates 21 as illustrated by the full lines in Figure 2. This hinge construction also prevents inward movement of the side walls beyond the straight line formed by their dotted line positions in Figure 2.

As before described, and clearly illustrated in Figure 2, the plates 21 formubut a portion of the floor or bottom of the body and have their inner longitudinal ends spaced to accommodate the movable or endless floor member 26. Member 26 comprises a plurality of slats or transverse plates 30 carried by links 31 of a pair of sprocket chainsl trained4 about sprocket wheels 22 and 33 mounted on shafts 34 and 35, journaled in bearings disposed adjacent the rear and forward ends of the sills 13.

One of the shafts mounting the endless floor sprockets is adapted to be driven by either manual or mechanical means to move the upper face of the endless floor portion toward the gate 20 to discharge the load and in the drawings a shaft 36 is connectable, by a clutch mechanism 27, with the truck power plant, not shown, to drive one of the sprocket shafts through a gear transmission 38 connected With a driven shaft 39 which is in turn connected with one of the sprocket tially equal to that o the movable floor portion and as the load is discharged from the body the movable side walls are adjusted to their dotted line positions to insure the complete emptying of the body. The side walls are adjusted by a shaft 42 mounted transversely of the body in bearings 43 secured to the center main beams 14 and having drums44'secured to the'ends thereof, `each j drum having the medial portion of a cable 45 secured thereto, the ends of which pass over guide pulleys 46, secured to the upper portions of the adjacent braces 16, and then downwardly and are secured, as at 47, to levers or arms 48 rigidly attached to the under side of the adjacent plates or sections 21. lVith this construction it will be readily obvious that rotation of shaft 42, through the medium of a hand crank 49 or any other suitable mechanism, winds vthe medial portions of thc cables 45 on the drums 44 shortening the cables and straightening the angle between the plates 21 and 22 to incline t e side walls toward the movable floor portion 26. In this manner all of the material is placed on the movable floor and thus readily discharged from the body.

' In handling coal, coke or other material, it is desirable to discharge the material directly into buckets, bags or other containers 49 for convenience in carrying it to a place of storage such as the basement of a residence and in Figure 3 I have illustrated an attachment for conveying the material as it is discharged from gate 2O and to a receptacle supporting platform of approximately shoulder height. If desired the conveyor 50 ma be employed to convey the material direct y to a place ofl storage or else have a chute, not shown, attached thereto for carrying the material to a manhole, basement window, or the like.

In this form of my invention an endless conveyer 50 of preferably the belt ty e having iiights secured thereto, is traine about pulleys 51 and 52 mounted on shafts 53- and 54 journaled in the ends of a frame 55 secured to the truck by the shaft 54 which is journaled in brackets or supports 56 de-v pending from the rear ends of the sills 13. The conveyer 50 is driven from a sprocket wheel 57 fixed to shaft 34 bya *sprocket chain or belt 58 trained about a sprocket wheel 59 fixed to shaft 54. The frame 55 is secured at the proper angle by chain or other brace means G0 having its inner ends or end secured to the body, as at 6l, and its outer end or ends secured at` the frame 55, as at 62,' a platform 63 for receiving the receptacles 49 being secured to the frame, as at 64, and braced by a chain or other means 65.

In Figures 4 to 7, inclusive, I have illustrated the application of the principle of my invention to a railway car of either the open or closed type in which two movable floor units 26 are provided adapted to dis; char e toward the center of the car into suit-a le discharge chutes and as the construction of this form of ml identical with that illustrate in Figures l 4to 3 with a few additions the description of Figures l to 3 itl is thought will suffice for Figures 4 to 7, with the following additions.

The central portions-66 of the side walls of the car are rigid and the portions ofx the side Walls outwardly thereof as previously described in connection with the truck device, and mounted between the inner ends of the end of the car is a movable the movable ioor device discharging into an lopening 67 between the fixed walls 66 from which a two-way spout construction 68 leads for discharging the load to either side.

The discharge spout is in the form of a trough having a discharge mouth 69 adjacent each side of the car and liingedly connected to a common shaft 70 are a pair of gate members 71, which, when in their positions illustrated in Figures 4 and 6, close the opening 67. Each gate member 71 has a lock or latch device 72 secured to its outer end for engagement in an opening or keeper 73, in the adjacent portion of the fixed walls 66 defining the sides of opening 67, when the gate is closed and which passes through an opening 74 in the bottom of the adjacent vchute 69 when open, as illustrated in Figure 6. In this form of my invention I have illustrated manual means for operating the movable floor members comprising a shaft 75 journaled between the center-most trans-.

verse beams 14 and carrying beveled gears 76 which mesh with beveled gears 77 mounted on the inner-most shafts 34 of the movable ioors, shaft 75- being rotatable by a ratchet lever 78 as illustrated in Figure 7,

a pulley 79 being provided on the shaft 75 in theevent it is desired to connect a suitable power unit therewith for mechanical operation.

In the eventit is desired to elevate the material from either discharge spout 69 to a truck or place of storage, a conveyor similar to that depicted in Figure 3 may be employed, but a portion of the conveyer be-l ing` illustrated by conventional lines.

From the above description taken in connection with the accompanying drawings it will be readily apparent to those skilled in invention is are adj ustable pairs of plates 21 in each floor device 96,v

the art to which an invention of this character appertains, that I provide means for discharging the load from a truck car body or the like which will greatly facilitate the .handling of the material and vat the same Adecrease the carrying capacity of the body.
